PALMATED SMOOTH-NEWT. 159 
tail is also lessened by about one-fourth of its vertical 
depth. The palmation of the hinder feet of the male is 
completely altered ; instead of being webbed like a duck’s 
foot, it has now each toe simply fringed with skin, and the 
fringes are joined at the bases of the contiguous toes. The 
ridges on the back do not alter, and the caudal filament 
remains undiminished.” 
The palmation does, however, in some instances remain, 
with scarcely any change, up to the commencement of 
winter. 
The colour of the male and its markings are somewhat 
duller in the winter than in the summer, but this change is 
much less considerable in the present species than in L. 
punctatus. The female, as in the other species, undergoes 
no seasonal change.
